If you’re looking for a plaster-based product to fill in cracks and holes in your walls, you might be tempted to grab a tub of Polyfilla. But does it work? And is it safe? We explore the answers below:
Can you use Polyfilla as wood filler?
Polyfilla is not suitable for filling cracks in wood. It is a type of plaster and, as such, it has a very porous surface that will soak up the water from the wood around it.
This can cause problems if you are using Polyfilla to fill any gaps or holes in wooden surfaces because it will absorb moisture from those surfaces and increase their size over time.
Polyfilla should only be used as an emergency repair method for small cracks/holes that have appeared on walls or ceilings after moving house or having them repaired by professionals after damage caused by water leaks etc., but there are better options available if you need something stronger than just putty which doesn’t require mixing before use like Polyfilla does (it seems like quite hard work!).

Can plaster filler be used on wood?
Plaster filler is not suitable for filling cracks in wood, as it will crack and flake off over time. Plaster filler is a decorative material that can be used on ceilings and walls.
It’s not waterproof, so it’s only suitable for indoor use. Plaster filler is also not suitable for use on exterior surfaces or interior surfaces where water may come into contact with the surface (such as bathroom tiles).
Can you use Polyfilla on skirting boards?
While Polyfilla is great for many DIY projects, it’s not suitable for skirting boards. This is because you need to use a filler that’s rated for exterior use if you’re applying it outside your home, and the same goes for wood that will be exposed to moisture.
Wood fillers will also provide better adhesion than Polyfilla.
Can interior filler be used on wood?
Polyfilla is not designed for use on wood, so it’s not a good choice if you have a large area of wood to fill. You would be better off using a filler made specifically for that purpose, such as a wood filler or drywall joint compound.
Polyfilla is designed for use on plaster and drywall, however, so it can be an excellent option if you need to repair cracks and holes in walls or ceilings.
Polyfilla comes in different sizes and colors like white or grey; choose the color that best matches your decorating scheme to ensure that your repair job looks professional!
How do you use Polyfilla timber filler?
- Mix the two parts of the filler together, using a putty knife or trowel to apply it to the damaged area.
- Sand the filler once it has dried (approximately 2 hours), using sandpaper that is no coarser than 120-grit.
- Apply another coat if necessary before sanding with finer sandpaper (such as 150-grit or 180-grit).
What can Polyfilla be used for?
Polyfilla is a type of plaster filler that can be used for many different purposes. It can be used to fill holes, cracks, and gaps in woodwork or even to fill screw holes.
You can also use Polyfilla as an inexpensive alternative to grout when tiling walls and floors. The key thing is that you need to make sure that your surface is clean before applying the Polyfilla otherwise it will not stick properly.
What is the difference between Polyfilla and wood filler?
Polyfilla is a plaster-based filler that works to fill holes, gaps, and cracks in walls between plasterboard sheets. It’s commonly used on windowsills, doorframes, skirting boards, and the like.
Wood filler is typically made from polyurethane or oil-based materials and can be applied with a putty knife or trowel. You can also apply it using a special applicator gun for larger areas such as window frames.
Wood filler remains soft for several hours after application so you’ll need to wait before sanding it down smooth with fine-grit sandpaper or steel wool.
Once dry, wood filler is hard enough for painting but some brands may be suitable for topcoat use without further preparation (check the label).
Polyfilla tends to set harder than wood fillers so you’ll need to let it dry out completely before reusing or sanding down if necessary – about 24 hours should do it!
What to use to fill wood cracks?
Polyfilla is not suitable for use on wood, as it can damage the surface of the wood and will not provide a secure finish. You should instead use a plaster filler that has been specifically designed for use with timber.
However, if you are looking to fill holes in plasterboard, then Polyfilla is ideal as it dries hard enough to hold its own weight and can be easily shaped using a putty knife or similar tool.
Polyfilla is a great product to use for filling wood cracks and holes. It’s easy to work with, dries quickly, and can be painted after drying.
As with any filler or plaster, however, it’s important that you take care when applying it so as not to damage your walls or furniture by over-applying too thickly, or using too much pressure when smoothing out the surface afterward.
If in doubt about how much Polyfilla should be used on your project then we’d recommend asking a professional before starting work!
